Peer Reviewed Journal. Abstract This study was conducted on a single cylinder four stroke cycle engine. Two different crankshafts from similar engines were studied in this research. The finite element analysis was performed in four static steps for each crankshaft. Stresses from these analyses were used for superposition with regards to dynamic load applied to the crankshaft. Further analysis was performed on the forged steel crankshaft in order to optimize the weight and manufacturing cost. Key words FEA,CAE Analysis, Dynamic Load analysis, cost optimization, Weight reduction, Crank shaft, Crankshaft Analysis, Cost and weight reduction. Reference1 Altan, T., Oh, S., and Gegel, H.
